der the felt on which the overlying glass is laid so as to providechannels between the felt and the underlying glass or other supportthrough which the water of condensation passes from'the inside face ofthe overlying sheet onto the outside face of the underlying sheet.

The invention also comprises the improvements to he presently describedand finally claimed.

To the following description reference will he made to accompanyingdrawing forming part hereoi and which Figure l is a sectional view takencrossof the invention. m

Fig. 2 is a. perspective view of. a crimped plate embodying features ofthe invention.

Tn the drawirg 1 indicates a crimped plate which may he made ofappropriate metal or material. The plate is provided with anchors 2 and,as shown, they are of the form of hoolrlilre legs. 3 indicates purlinsupon which the underlying sheets ioii corrugated glass are supported.The overlying sheets 5 of corrugated glass in Fig. 3 rest upon strip offelt or thelike 6, which in turn rests upon the underlying sheets ofglass in the structure shown in Fi at, the sheets oi glass rest upon sfiller strap 7 conforming to the corrugations in the glasaand it issupported upon a strip of felt 6 which mturn rests u on a purlin 3.lncldentally it may he said t lat the devices 8 and 9' prevent the glassfrom sliding endwise oh? the root, and the device if s. dashing.

The crimped or corrugated plate or element 1 underlies the strip of feltor the like 6 and in the felt and the crimps provide open passagesindicated at 11. Water of condensation on the ini. face of the sheet ofglass 5 at the righthand in Fig. 1, runs out through the passages 11onto the outer face of the underlying sheet of glass 4%, and water ofcondensation from the under face of the sheet 4 runs out throughpassages 11 at the left in 1 outside of the dashing 10. In this Way goodI and efiicient drainage is provided.

It may be remarked that the anchors 2 provided on the crimped plate 1are spaced apart and arranged at the side edges near one end of theplate and when this is done they serve their purpose as anchors withoutinterfering with the drain passages ll.

in referring to felt or the like in connection with the element 6, theintention in both the specification and claims is to include anymaterial into which the crimped elements 1 may be embedded insubstantially the mannor described.

The strips 6 and fillers '3 may he spaced from the top edges of thepurlins, and when this is done pockets 1% are provided between thestrips, p'urlins and underface of the glass, and these pockets mayaccumulate moisture of condensation which finds way to the outside bythe channels ll.

It will be obvious to those skilled. in the art to which the inventionrelates that rnoditications may he made in detail of construction andarrai-lgeme nt and matters of mere form without departing trons thespirit of the invention which is not limited to such matters orotherwise than the prior art and. the appended claims require.

tion parallel to the axis of the hoo I claim:

1, For roofs or skylights having a strip of felt upon which corrugatedglass is laid, drainage means com using a crimped plate arranged underthe elt strip and provid ng drain channels, said crimped plate havmg atone end marginally arran ed space hooklike legs enga 'ng the roostructure, the crimps in said p ate extendingiin a direced portion ofsald legs.

2. In a sloping roof or skylight structure the combination of acorrugated sheet of glass, a support for the corrugated sheet of glass,a felt strip interposed between the sups port and sheet of glass, and acrimped plate embedded in the strip of felt and providing drainagechannels, the crimps in said plate sloping parallel to said roof.

3. In a sloping roof or skylight structure the combination of acorrugated sheet of glass, a support for the corrugated sheet of glass,a felt strip interposed between the support and sheet of glass, and acrimped plate embedded in the strip of felt and roviding drainagechannels, said crimped p ate having anchors that engage the support andthe crimps in said plate sloping parallel to said roof.

n a sloping roof or skylight structure i the combination of purlins,strips superposed v on and spaced from thetop edge of the purlins,corrugated sheets of glass supported onthe strips, there being pocketsprovided between the tops of the purlins and the glass and the stri sfor the accumulation of moisture of con ensation, and crimped platesarranged on top of the purlins and under the strips providing drainagefrom the pockets, the crimps in said plates sloping parallel to saidroof. I

5. In a $10 ing roof or skylight structure the combination of purl-ins,corrugated sheets of glass supported on said purlins and spacedtherefrom, there being provided ockets between the tops of said purlinsan said glass for the accumulation of moisture of condensation, andcrimped plates having longitudinal crimps therein slopin roof arrangedbetween sai purlins and said glass to provide drainage from saidpockets.
